Solve 2*4*3.14*10+2*4^2*3.14=

$$2 \times 4 \times 3.14 \times 10+2 \times { 4 }^{ 2 } \times 3.14=$$

Evaluate

$$351.68$$

Solution Steps

Multiply 2 and 4 to get 8.

$$8\times 3.14\times 10+2\times 4^{2}\times 3.14$$

Multiply 8 and 3.14 to get 25.12.

$$25.12\times 10+2\times 4^{2}\times 3.14$$

Multiply 25.12 and 10 to get 251.2.

$$251.2+2\times 4^{2}\times 3.14$$

Calculate 4 to the power of 2 and get 16.

$$251.2+2\times 16\times 3.14$$

Multiply 2 and 16 to get 32.

$$251.2+32\times 3.14$$

Multiply 32 and 3.14 to get 100.48.

$$251.2+100.48$$

Add 251.2 and 100.48 to get 351.68.

$$351.68$$

Factor

$$\frac{7 \cdot 157 \cdot 2 ^ {3}}{5 ^ {2}} = 351\frac{17}{25} = 351.68$$
